IMPROVEMENT IN JOURNAL-BOXES.

Specification forming part of Letters Patent No. 12,525, dated September26, 1876; application filed August 14, 1876.

l To all whom t may concer-n.:

Be it known that I, WM. H. LUNGREN, of the city of Wilmington, countyot' New Castle, State of Delaware, have invented anew and usefularrangement of preventing' axle-journals from heating, uneven turning orwear, which is fully set forth in the following specitcation, referencebeing had to the accompanying drawing.

The arrangement relates to journals and bearings of car-axles; andconsistsin interposing a loose liner of lead or other soft metal betweenthe axlejournal and hard metal bearing.

' Theobject of myinvention is to prevent the heating" of railroad-caraxlejournals, when caused by uneven wear or improperly-turned journals,or.l from concave wear of journals, any or all ot which would cause anuneven bearing. W

I use any ordinary metal bearings, made of brass, composition, or iron,rough, as they come from the fonndery, and insert between the bearing Aand axlejournal C a loose lead liner, B, made ofsheet-lead or other softmetal. These lead liners B are made from merchantable sheet-lead ofproper thickness-say, from one-sixteenth to one-tenth of an inch-cut tosuch size as will cover entire the inner side which may be caused by' ofmetal bearing A, as shown in Figures 1 and 2 of accompanying drawing.

By use of the loose soft-metal liner B between the bearing A andaxle-journal C any unevenness in journal C or bearing A is compensatedfor by yielding of softmetal liner B.

I am aware that lead, Babbitt, or soft composition has been used to facebearings for carjournals; but in all cases where the faces wear, thebearings have to be renewed entire, as the worn ones have to be takenout to reline; but by my invention you need not remove the bearing, butonly replace the movable lead 4 liner, which can readily be done, andwhich remains in place withoutV any mechanical attachment.

I claim as my invention- The loose liner of soit metal between caraXlejournals and hard-metal bearings, so arranged that they can be removedand replaced at pleasure, and thereby prevent the heating of journalscaused by any unevenness from wear or otherwise, substantially asdescribed.
